To all whom it may concern;

Be it known that I, lnvING D. STEVENS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful,

Improvements in Fountain Shaving-Brushes, of which the following is a specification.

' My invention relates to fountain shaving brushes having a` hollow handle forming a reservoir for containing a supply of liquid soap, and provided with means for ejecting liquid soap from the reservoir into the bristle portion of the brush.

Objects of m invention are to rovide means for ra i y e'ecting a suitab equantity of li ui soap om the hollow handle into the ristle portion of the brush; to adapt the ejecting means to also serve as a valve for closing a port arranged for discharging liquid soap into the bristle portion of the brush to adapt each action of the ejecting device to eject a uniform quantity of liquid soap from the. reservoir into the bristle portion of the brush; to provide a combined valve and ejector for opening and closing a port between the reservoir and the bristle portion of the brush, and operating to eject a predetermined or substantially redetermined quantity of liquid soap into the bristle portion of the brush as an incident to each action of the combined valve and ejector to rapidl and forcibly eject a suitable quantity o liquid soap into the bristle portion of the brush to rovide a device whlch can be easilyand rea ily operated; and to provide a simple, practical and desirable construction.

In the accompanying drawing: Figure 1 is a central longitudinal section through a fountain shaving) brush embodyin my invention,

the piston eing shown in e evation in full lines, and its position when it is drawn back so as to open the port or ports of the feed tube being indicated in dotted lines, the reservoir formed by the hollow handle being substantially full of liquid soap. Fig. 2 is a transverse section on line .ft-:1: in Fig. l. Fig. 3 is a central longitudinal section on a plane atright angles to the plane of Fig. 1, the plane of Fig. 3 being indicated by dotted line l-il in Fig. Il, and the reservoir being empty. ln this figure the combined valve and piston is shown in full lines and is drawn back so as to open communication between the tube or barrel for the piston, and the interior of the reservoir. Fig. 4 is a section on dotted line 3 3 in Fig. 3.

The brush handle A is constructed with a; hollow cylindric portion l formin the main portion of the handle and adapte to form a reservoir for the liquid soap. This hollow handle portion. 1 is provided at one end with a partition or end wall 2, having a central opening and a downwardly projecting annular liange 3 along the margin of such opening and forming a ni ple into which is securely iitted the feed tu e B. The lower ortion 4 of this feed tube B projects below t e nip le 3 and extends into the brush E to a suita le l extent substantially as illustrated. The feed tube B also extends from the end wall 2 toa suitable extent within the reservoir, and this portion of the feed ltube which thus extends within the reservoir is provided with slots forming lateral openings 5, 5, whichA are best shown in Fig. 2. These lateral openings 5 constitute inlet ports which are exposed within the reservoir and arranged to receive liquid soa directly from the chamber formed by the hoow handle portion l.

As a means for opening and closing the inlet port or ports and for forcing soap downwardly through the tube portion 4, and also for closing tube portion 4 when desired, l provide a piston C arranged within the feed tube and having a stem 6 which is arranged to work through an opening in an end cap D, said end cap being screwed u n what may be termed the butt end of the hollow handle. In Fig. l the piston is in position to close the inlet ports 5, and as therein shown, it extends downwardly into the tube portion 4 so as to render the closure more perfect. When it is desired to admit liquid soap into the feed tube, the operator will draw the piston back as indicated in dotted lines, whereby it will clear the ports 5 and thereby open the same. As soon as a suitable quantity of liquid soap has entered the feed tube by way of the inlet port or ports, the operator will push the iston forward to .the position shown in full ines in Fig. 1, thereby closing the inlet ports and forcing the liquid soap into the brush E.

y ates as an ejector, and by givin it'a quick motion, the liqgid soap will e forcibly ejected into the rush and suitably didused therein, and hence, the action is reliable and ra id.

IlVhen desired the ca D can be unscrewed so as to open the han e and permit it to be charged with liquid soap.

The device thus constructed can be readily o cned and cleaned and supplied with a fresh c ar e of liquid soap, it being seen that it will onl e necessary to unscrew 'the end cap or co ar D, and then remove said cap and the iston from the brush. The tube or piston barrel B is of suitable length to permit the lower or forward end of the piston to remain' within the barrel when the pistn is drawn back until the stop I on the piston engages an abutment d on the inner side of the cap or collar. When the iston is drawn back as in Fig. 3, its action tend to draw li uid soap from the reservoir into the piston arrel B through the lateral inlet ports in said barrel. When the piston is forced forward, it will rapidly close the inlet port or ports 5 and cut olf the same before the piston can force any undesirable quantity of liquid soap out through the ports 5, and moreover, when the piston is drawn back, some of the liquid soap will follow the iston and some of the liquid soap williind lts way into the discharge port formed by the tube or nozzle 4, which is substantially an extensionof the piston barrel and which also forms a socket or barrel portion into which the lower end portion of the pistoncan be forced when it is desired to close the discharge port or tube 4, as in Fig. 1. vThe piston, the barrel and the discharge tube or nozzle 4, are all arranged along a central longitudinal line within the brush, and as the discharge' tube or nozzle 4 is centrally within the brist e portion of the brush, the liquid soap ejected from such discharge tube or nozzle will be diused within the said bristle portion. The piston is 'a sliding, reciprocating piston and has what may be termed a suction action, and an ejecting action in alternation. The suction action of the piston tends to draw liquid soap within the piston barrel While the ej ecting action of the piston closes the inlet port or ports of its barrel and ejects the contents of the barrel into the bristle portion of the brush. The cap D at the upper end of the hollow handle can be easily unscrewed, and thereu on the piston and th'e cap can be removed or either cleaning or illing the reservoir. The cap has a central bearing portion d through which the piston stem 6 is fitted to slide, and when the piston has been raised to the desired limit of its up stroke, such movement will be checked by the engagement of its stop I .with the lower end of the bearing portion d. VBy this arrangement the piston can have a determined length of up stroke.

It will be observed that a feature of importance' lies in having the plunger closely fit the ejection tube whereby the use of a valve for the exit is rendered unnecessary. Dis ensing with a valve not only cheapens an renders practical the constructlon but also enables me to employ as the exit a pair of longitudinal slots arranged at opposite sides of the tube, this arrangement of exit slots being desirable in that they insure a quick iilling of the ejection tube 4 and render clogging of the exit impossible even where the soap is somewhat thickened or congealed.

Another feature of im ortance lies in extending the ejection tu e 4`a considerable distance beyond the end of the plunger when the same is at the extremity of its ejecting stroke.` This prevents the entire charge being ejected into the bristles on the e'ecting stroke, about one-half the charge bemg retained in the tube whereby this remaining art'of the charge will be fed out gradually by the working ofthe bristles during the act of rubbing up the lather on the face, whereby the lather may be worked up and distributed over the bearded portion of the face more evenly and expeditiously.

What I claim as my invention is:

A fountain shaving brush having a hollow handle forming a suppl chamber for liquid soap and provided and'normally closed at one end with a removable end ca for closing over the upper end of the supp y chamber, and also for openingV the upper end of the supplychamber to permit a supply of liquid soap to be introduced into the handle by way of its upper end, the cap being also provided with a central bore for a piston stem, and the opposite end portion of said handle being provid^d with a artition forming a bottom end -for the supp y chamber and having forward of such partition a socket in which the upper' end portion of the bristle part of the brush is secured; a piston tube arranged axi- -ally within the supply chamber and extendA ing down through the bottom end of the su ply chamber into the bristle portion of t e rush to Yan extent to penetrate such bristle portion of the brush beyond the outer end of the bristle socket, the portion of said piston tube or barrel within the su l chamber being provided with o posite y disposed longitudinal slots exten g upwardly from the bottom end of the supp chamber and a piston iitted closely and a apted to reciprocate in saidtube or barrel and forming the sole means whereby the longitudinal slots in said barrel are opened and closed and by which the charge which is admitted direct from the supply chamber into the piston barrel is forced down into the bristle portion of the the charge of liquid soap will temporarily brush, said plun er or piston being provided remain within the lower end portion of the -10 with a stem wor ing through the upper end tube.
